A terminal connection component including press-fit terminals and terminal metal-fittings. The press-fit terminals have a plate shape in which a taper is disposed at one tip, and the terminal metal-fittings also have a plate shape in which a fitting section is disposed at one end side. The fitting sections of the terminal metal-fittings have a first hole part and a second hole part from the one end in parallel. The tips of the press-fit terminals are press-fitted and are connected to the fitting sections of the terminal metal-fittings, and a portion between the first hole part and the second hole part of the fitting section, which serves as an elastic deformation section, is elastically deformed in a thickness direction of the press-fit terminal and biases the press-fit terminal so that the press-fit terminals are surely press-fitted to the fitting sections of the terminal metal-fittings.

Terminal connection component, and terminal connection structure between control unit using the same and motor

A connector housing includes a hole having a minimum size that a lead section of a connector terminal to penetrate, and a guide wall which is formed along an outer peripheral of the hole, and is protruded in a direction which a lead section protrudes from the connector housing to a bending section of the lead section, wherein, by which inner walls of the guide wall is mutually and directly in contact with side surfaces of the lead section over a height near a top end side of the lead section in a bending section of the lead section from an outer peripheral of the hole, a sealing structure is formed from the bending section of the lead section to an interior of the connector housing.

Connector

Multipolar lead parts having plural leads and a retaining member, wherein the retaining member includes a cylindrical portion so as to cover peripheries of the leads, the cylindrical portion facing in a board direction; wherein the leads each include an upper-side board coupling portion and a lower-side board coupling portion; wherein the lower-side board coupling portion comprises a forward protruding portion that the other end side of each of the leads is bent in a direction orthogonal to an arrangement face of the leads, a vertical portion extending downward from a front end, a solder coupling portion extending backward from a lower end, and a rising portion extending upward from the solder coupling portion; and wherein said rising portion is formed as to have an obtuse angle from said solder coupling portion regardless of a bending angle of said vertical portion with respect to said solder coupling portion.

Multipolar lead parts and board coupling device

A motor controller and a production method thereof are provided to be capable of lowering the stress applied to joint parts of terminals and a board as much as possible, even if a thermal load or external force is applied to the connector, and in addition, capable of achieving a sufficient coupling strength when arranged in proximity to the electric motor. In the motor controller, there are provided: a first securing section () and a second securing section () configured to secure a connector () to the case () at an outer circumference of a connector housing () of the connector (); and a positioning section () configured to position the connector () to the case (), when the connector () is inserted into the connector receiving depression section ().

Motor controller and production method of the same

There is provided a connector capable of realizing simple assembly and prevention of entering of foreign matter. A connector terminal () includes an insertion part () that has a terminal metal fitting to be electrically connected with an external connection terminal, and a pin () fixed to the insertion part () and has a bent shape. The connector terminal () is held by a connector housing (). In this situation, the connector housing () has a hole () that has a size at which the pin () can penetrate from a tip side, and a guide wall () formed along an outer circumference of the hole () and projects in a direction in which the pin () projects from the connector housing ().
